Overview ¶
Package api implements the general Klaytn API functions.
Overview of api package ¶
This package provides various APIs to access the data of the Klaytn node. Remote users can interact with Klyatn by calling these APIs instead of IPC. APIs are grouped by access modifiers (public or private) and namespaces (klay, txpool, debug and personal).
Source Files
- addrlock.go : implements Addrlocker which prevents another tx getting the same nonce through API.
- api_private_account.go : provides private APIs to access accounts managed by the node.
- api_private_debug.go : provides private APIs exposed over the debugging node.
- api_public_account.go : provides public APIs to access accounts managed by the node.
- api_public_blockchain.go : provides public APIs to access the Klaytn blockchain.
- api_public_cypress.go : provides public APIs to return specific information of Klaytn Cypress network.
- api_public_debug.go : provides public APIs exposed over the debugging node.
- api_public_klay.go : provides public APIs to access Klaytn related data.
- api_public_net.go : provides public APIs to offer network related RPC methods.
- api_public_transaction_pool.go : provides public APIs having "klay" namespace to access transaction pool data.
- api_public_tx_pool.go : provides public APIs having "txpool" namespace to access transaction pool data.
- backend.go : provides the common API services.
- tx_args.go : provides API argument structures and functions.
